Teen hospitalised in weekend booze blitz

A 13-YEAR-OLD girl has been hospitalised and almost 550 people have been arrested during a weekend crackdown on alcohol-related violence.

Following an annual two-day police operation targeting alcohol-related violence in Australia and New Zealand, NSW police said arrests were up in the state.

While last year's blitz saw more than 380 people arrested over two nights, this year almost 550 people managed to get themselves "so drunk, or so out-of-focus that they got themselves in strife and got themselves arrested", Deputy Commissioner Nick Kaldas said on Sunday.

"What we are seeing more and more is that when people do get out and don't have a plan for getting home they end up presenting themselves as victims rather than offenders as well," he told reporters in Sydney.

Among the "victims" was a 13-year-old girl who was found by police passed out in the backyard of a Bellevue Hill home in Sydney's eastern suburbs.

Police said the girl had allegedly consumed a "large amount of vodka" at a party of more than 250 teenagers.

The girl was taken to Randwick Children's Hospital in a stable condition.

At Kings Cross, Sydney's nightclub district, three men were arrested after a brawl broke out at around 1.45am (AEDT).

Meanwhile, in Ballina in northern NSW, a police officer was allegedly assaulted after a man was refused entry to a licensed hotel due to intoxication.

The 36-year-old is expected to be charged with assault police and resist arrest.

"Despite the community's best efforts to curb alcohol-related violence and anti-social behaviour, it's clear some people just aren't getting the message," Mr Kaldas said.

"There is definitely a culture of binge-drinking where people go out not only with the aim of having a few drinks but getting absolutely drunk.

"This is not seen and should not be seen as purely (a) law enforcement problem ... you can't arrest yourself out of these figures.

"The community has to accept some responsibility."

Mr Kaldas said although Queensland has had a "marked drop in arrests", NSW did not greatly differ from other Australian states and territories.
